I am trying to port the asterisk voicemail in an embedded linux
environment. I want to store the voicemessages in 3 formats (G726, ALAW,
ULAW and possibly G729 in future). This option is available in the Asterisk
voicemail, however I want to store the message in any one of the above
format(in a file) and transcode or convert in to other formats i.e. to other
files at a later stage due to MIPS constraints. Hence below are the
question and I will much grateful if u can answer my below questions:
1. How to go a head with this i.e. converting one file in to other files of
2. I see in the conversion/transcoding is done at the time of recording, so
I want to schedule a idle thread to do the conversion, in this case how can
I convert from like alaw <=> ulaw, alaw<=>G726, alaw <=>G729 etc
I am new to codecs or compression technologies with no electronics
background, please help me in this matter.
